Shakardokht (Shakar) Jafari is a Medical Physicist and an award-winning innovator based at the Innovation Space, Portsmouth University. She developed an efficient and low cost method of measuring a medical dose of radiation and became the CEO of Trueinvivo, a UK-based start-up medical device company working on providing multidimensional arrays of micro silica-based thermo-luminescent detectors (TLDs) [DOSEmapper™] to vastly improve radiation detection and measurement for radiotherapy and other related technologies. Shakar also works at the Queen Alexandra Hospital, Portsmouth, as a clinical scientist and as a researcher at the University of Surrey. Shakar was born in Afghanistan but the family was forced to leave when war broke out, settling in Iran where she completed her BSc in radiation technologies at Tehran Medical University and Tabriz University of Medical Sciences. After moving back to Afghanistan in 2004, Jafari taught in the Kabul Medical University and completed a master's degree in radiation physics there while working. In 2010 she moved to the University of Surrey to study a master's in medical physics and in 2015 she became the first Afghan woman to earn a PhD in Medical Physics.
